CVE-2026-21683

8.8

International Color Consortium · iccDEV

A type confusion vulnerability in the iccDEV library's EvaluateProfile function allows for potential memory corruption when processing malicious ICC color profiles.

Executive summary

The iccDEV library contains a type confusion vulnerability in versions prior to 2.3.1.2, which could allow an unauthenticated attacker to cause total system impact through crafted color profiles.

Vulnerability

This is a type confusion vulnerability residing in the icStatusCMM::CIccEvalCompare::EvaluateProfile() function. The flaw allows an unauthenticated attacker to trigger memory corruption by providing a specially crafted ICC color profile to an application utilizing the affected library.

Business impact

The identified vulnerability poses a high risk to business operations, as it allows for unauthorized code execution or system instability. With a CVSS score of 8.8, this flaw represents a significant threat to data integrity, confidentiality, and system availability. Organizations relying on this library for image processing or color management should treat this as a high-priority remediation task to prevent potential exploitation of their software stack.

Remediation

Immediate Action: Update the iccDEV library to version 2.3.1.2 or later immediately to incorporate the provided security patch.

Proactive Monitoring: Review application logs for crashes or unexpected termination of processes that handle ICC profile parsing, as these may indicate exploitation attempts.

Compensating Controls: Implement strict input validation or sandboxing for any application that processes third-party ICC profiles to restrict the impact of potential memory-based attacks.

Exploitation status

Public Exploit Available: No

Analyst recommendation

Given the high CVSS severity score and the potential for total system impact, immediate action is required. Organizations must verify their software dependencies to determine if they are utilizing the vulnerable iccDEV library and apply the version 2.3.1.2 update as soon as possible. Failure to patch these libraries leaves host applications vulnerable to memory corruption attacks triggered by malicious image or color profile files.
